As noted in this MacWorld article “Apple Support gets its own standalone iOS app,” there’s now an Apple Support app for your Apple mobile devices which provides convenient customer service and support for all your Apple products.
Previously, you were able to use the Apple Store app to get support and schedule appointments at the Apple store, but it was an afterthought. … Apple Support comes just before the busy holiday season—when lots of people are bound to unwrap new Apple products. This new app makes it easier for these new customers to get answers and see if their issues can be resolved from home, without having to go in to an Apple store. That gives Apple employees more time to handle issues that do require in-store support.
Every time I’ve visited an Apple Store there’s been lots of people getting help in the back. You might want to try the new Apple Support app before getting in your car next time. It’s free.
